That's a nifty little pump. I have plenty of pressure tanks, both 4 and 6 gallon, but shortage of double line fittings. Can you even SHIP tanks now? Let me know what you decide.....I check this forum usually twice a day. Probably have 25 pressure tanks in stock.......but also potential motors that need work. I very often can get a motor pretty cheap, but no tank with it.....so I keep extras on hand. They are all sterile and dry inside.....no rust.
Double fuel/air line is still available for a few bucks a foot......so not bad. Then you will NEVER EVER worry about a fuel pump going bad. The closed pressure system also makes it very hard for moisture to get into your fuel. Why? If your tank leaks.....your motor doesn't run. Why do they have to get rid of all the "good stuff"?
